Find what slipped.Get it resolved.
5 projects
Every gap comes with the records behind it and a follow-up ready for you to approve. Works on top of Procore, QuickBooks, Sage and Siteline, so there's nothing to replace.
Why money goes missing
Most of it isn’t lost in one big mistake. It falls between systems.
A change order is approved in one place, the schedule of values lives in another, and the pay app goes out from a third. Main reads all of them together and flags the gap so you can confirm it.
Main never sends anything or moves money without your approval.
Four checks.One set of exports.
What it checks
Change orders
against the bill
Every approved change order is looked for on your schedule of values and on each pay app since it was approved. When it isn’t there, Main flags the gap so you can confirm it.

Who can see our data?
Accounts are created only by ordering at /start or by invitation. A paid order at /start creates your organization and its owner account. Everyone else is invited by their organization’s owner or by Main. You sign in with email and password. Sensitive actions ask for your password again. Each organization’s data is kept apart in the app and again in the database. This is tested on every release. Files are encrypted with a key that belongs to your organization alone. Main staff see your data only through a logged workspace session with a stated reason. An activity log records what happens, and entries can only be added, never changed. Main does not claim any security certification. A mutual NDA is available before you send anything.
Do you connect to our systems?
Main works from exports you already produce — from Procore, Sage, QuickBooks, Viewpoint, Excel, Siteline or Clearstory. No integration or new system is needed to start; read-only connections are optional and come later. Main sits above those tools and does not replace them or write back to them.
What are the four exports?
Send the exports you already produce. That means your change-order log, schedule of values and payment applications. Add your A/R aging or invoice register, payments and retainage ledger. Any CSV or Excel file works (.xlsx, no macros). Your column names don’t need to match; you confirm the mapping once. With just a change-order log and pay application lines, Main can already check whether approved changes reached billing. WIP and job-cost data are optional.
What happens if it finds nothing?
We examine the agreed records, cite every finding, and disclose anything we couldn't assess. If we can't complete the agreed review, you get a refund. To ask for it, email Main. The full policy is at /revenue/refund-policy.
